'STOPPER Filed Aug. 29, 1928 INVENTOR mused Jul. 27, 1931 UNITED STATES JOHN E. manna, or mew YORK, n. srorrnn Application filed August 29, 1928. Serial No. 803,805..

vide a stopper which may be sealed on the.

outside by a metal clip to counteract. any pressure of the contents which would tend to cause it to esca e from the container through the orifice of t e stopper.

A further object of the invention is to provide an instrument having a tip which can be inserted into crevices and which isprovided with an orifice to eject the contents of the container into places which ordinarily cannot be reached otherwise and in which the flow can be made continuous.

A still further object is to provide the stopper with flexibl'e projections to be used like a brush and a round projection like a plug for sealing a container hermetically.

In the accompanying drawing, Figure 1 is a sectional sideview of the stopper attached to a container with the clip detached therefrom and shown in front of stopper. Figure 2 is a top plan .view of the stopper of Figure 1. with the clip in a correspon ing position. Figure 3 illustrates a modification of my 1nvention in which the stopper is shown in side elevation attached to a bulb. Figure 4 is atop plan view of the device shown in Figure 3. Figure 5 is ,a front end view of the ,f o stopper shown in Figure 2, the clip being omitted. Similar numerals refer to similar parts in all the views. g

- The nozzle is preferably constructed of flexible rubber in which 1 is the point which 5 is moulded cl'osedbut marked with a line 2 across the flat'side indicating where the nozzle should be cut or perforated with shears :or tool, this opening duct 3 therein. The

tubular duct 3 is fiat at its discharge end and round at the back where the rubber is b also much thicker and the nozzle enlarged as shown at 4 to fit a container as a plug.

The inside of duct 3 is further provided with an intermediate or inner nozzle 5 which is open,.and through which a metal screen 6 is 5 forced to occupy a position as shown, so that no liquid can be forced from the discharge nd towards the back, as the inner nozzle forms a check. The object of screen 6 is to prevent the insertion of a tube from point 1 through intermediate nozzle 5'. To illustrate the operation of the nozzle, I have shown it cemented to the discharge end 17 of a collapsible tube 18 such as is commonly used in the drug trade,jbut it may likewise be attached to any container or source ofliquid semi-liquid paste or the like on which a pressure can be exerted at will to force it through the nozzle.

In order to insure the self-closing of the flat point of the nozzle, the rubber is moulded. with lateral Fins 7 and 8 on each side of the nozzle, and to make these useful for cleaning purposes, they are notched out, forming a flat soft comb-like brush as shown.

The orifice at point 1 after it is cut is normalliy) closed, but if the container is used for a su stance such as paste,-the material re- -maining in the orifice maybe the action of the air solidify, and'to avoid this a suitably shaped-clip 9 is provided which fits over the point of the nozzle and encloses the tip by pocketlO formed in said clip. The clip may furthermore be provided with a knife edge 12 to provide a means of cutting the nozzle on line 2 as heretofore referred to. The cl p is preferably wider at the base 11 on which it may stand and hold the stopper in an inverted position. The plug end 4 at the back of stopper hereinbefore referred to is preferably round and adapted to fit into a container which is intended to be 'a sterilizer for cleaning or dipping the point of the stopper. It is, however, understood that this --plu'g end 4 may also be used as a stopper in the container from which the contents may be forced through'd'uct 3 of sto per.

In Figs. 3 and 4a celluloi or the like clip 14 is directly fastened to the stopper byia utton or projection15 formed on the stop- Q pressure, and

per, the clip having'an opening 16 therein which is adapted to engage over said button. The clip int is case serves as a shield as well as an outside protection to the discharge and of the nozzle and thus may also serve as a dro per for medicine or the like,

aving thus described my invention, what I claim as new and desire to cover by Letters Patent is: a 1. A flexible rubber nozzle having in its interior a duct and on its exterior a lurality of longitudinally extending finike projections,

avin a toothed edge.

2. K flexible rubber nozzle having in its interior a duct and on its exterior a pair of diametrically opposed longitudinally extending fin-like PIOJGCtiOIlS ered edges;

3. A flexible rubber nozzle having a duct therein, one end of which is normal y closed and adapted to open to provide an orifice of emission upon t e application of internal a check valve within said duct rearwardly of said normally closed end.

4. A flexible rubber nozzle havin a duct therein, one end of which is normal y closed and adapted to open to rovide an orifice'of emission upon t e app ication of internal pressure, and a check valve within said duct rearwardly of said normally closed end, said check valve being formed integrally with the flexible rubber nozzle and being adapted to also open upon the application of internal pressure thereagainst.

5. A flexible rubber nozzle havin a duct therein, one end of which is normal y-closed and adapted to open to rovide an orifice of emission upon the ap cation of internal pressure, and a secon ary nozzle within the duct, said secondary nozzle having a slit in its end providing a check valve within said duct.

6. A flexible rubber nozzle havin a duct therein, one end of which is normafy closed and adapted to open to rovide an orifice of emission uponthe app ication of internal pressure,- a check valve within said duct rearwardly of said diaphragm screen within said duct between the check valve and the normally closed end.
